We are looking for a Senior Engineer to help strengthen the quality engineering foundation for our SDK. This role focuses on building robust automation, scalable CI/CD systems, effective test strategies, and practical tooling that improves confidence in SDK delivery across multiple platforms.

You will work across several SDK teams to understand quality risks, improve workflows, and turn broad or ambiguous problems into useful engineering outcomes. This is a senior engineering role, so we are looking for someone with strong technical judgement, ownership, and the ability to make progress in complex environments. You do not need to have worked with every tool or domain listed below, but you should have strong fundamentals, be comfortable learning unfamiliar technical areas, and be able to apply that learning to real engineering problems. 

What you’ll be doing

• Building and improving CI/CD pipelines that support SDK build, test, and release workflows.
• Developing Python-based automation and tooling for test orchestration, system validation, diagnostics, and reporting.
• Creating, maintaining, and improving automated tests across unit, integration, system, and end-to-end levels.
• Investigating issues across build, test, deployment, and execution environments, and improving the reliability of the workflows around them.
• Supporting Linux and Windows development environments, including cross-platform scripting, automation, debugging, and build/test workflows.
• Applying test frameworks, quality metrics, and reporting approaches to improve quality visibility and support practical test strategy.
• Working with SDK teams to clarify quality risks, align on shared initiatives, and turn broad goals into actionable engineering work.
• Identifying bottlenecks, fragile processes, gaps in automation, or weaknesses in test coverage, then driving pragmatic improvements with the teams involved.
• Building domain knowledge across SDK areas through planned rotations or focused assignments, contributing useful improvements in new technical contexts.
• Balancing immediate delivery needs with longer-term improvements to SDK quality engineering practices, CI/CD reliability, and test effectiveness.
• Coordinating with teams across London, Bristol, and Dublin, including occasional planned travel where useful.
• Mentoring peers, sharing best practices, and helping influence quality engineering approaches across teams.

What we are looking for

• Strong practical Python skills for engineering automation, tooling, diagnostics, or test orchestration.
• Experience building, maintaining, or improving CI/CD, build, test, release, or deployment automation, using tools such as Jenkins/Groovy or equivalent systems.
• Experience developing, maintaining, or improving automated tests or test infrastructure, ideally across more than one level of testing.
• Ability to diagnose and resolve issues across complex build, test, CI, deployment, or execution environments.
• Comfortable working across Linux and Windows development environments.
• Familiarity with test frameworks such as pytest, GTest, or similar, and an understanding of quality metrics, test reporting, or practical test strategy.
• Ability to work with ambiguity: asking good questions, identifying risks, breaking broad problems into practical steps, and making sound engineering decisions when not every detail is defined upfront.
• Pragmatic engineering judgement, including knowing when to build a robust long-term solution and when to deliver a focused improvement that unblocks progress.
• Clear communication and collaborative problem-solving, especially when working across distributed teams, resolving unclear ownership, and advocating for quality engineering concerns.
• A willingness to take responsibility for quality engineering improvements, including proposing practical options, implementing changes, and following up with the teams involved.

Useful additional experience

Experience or awareness in one or more of the following areas would be useful, but we do not expect expertise in all of them:

• Languages such as C, C++, C#, or Rust.
• Build systems such as CMake or similar.
• .NET development or testing workflows.
• Container, Kubernetes, or VM-based environments.
• Desktop application testing.
• Graphics APIs or graphics-adjacent testing.
• AI/ML, MLOps, or data-driven quality workflows.
• Large-scale test infrastructure, reporting, or quality analytics.

About your background

We know strong engineers come from many different career paths. You do not need to match every item in this advert to be considered. The most important experience for this role is practical engineering work in automation, CI/CD, test infrastructure, quality-focused tooling, or complex technical debugging.

We are looking for someone who can operate at a senior level, work well with others, and help raise the quality engineering bar across SDK teams. If that sounds like work you have done, or a natural next step from your experience, we encourage you to apply.
